    Ground Investigation Report, Cornwall

    A Ground Investigation Report, fulfilling the requirements set out in BS EN 1997-2: Ground Investigation & Testing, was produced for an extension to a school in Dorset. The Ground Investigation Report (GIR) presented a factual record of the ground and groundwater conditions encountered, together with the laboratory testingresults, followed by a review of the ground profile and geotechnical parameters for foundation design. The Ground Investigation Report was issued promptly, shortly after the receipt of the laboratory testing results, less than three weeks after the completion of siteworks. Interim parameters for design were provided prior to the receipt of the laboratory testing results, based on field observations and in-situ testing results.

    Temporary Works Excavation Stability Assessment, North Devon

    It was proposed to construct a retaining wall as part of the proposed redevelopment of a residential site in north Devon. Ruddlesden were commissioned to provide a method statement detailing precautions to be taken during excavations, with details of the support to be provided during temporary works and construction of the retaining wall. Whilst it was considered that one of the excavations could be safely graded back to a safe angle of repose to facilitate the construction of the retaining wall, where this was not possible, the soils and rock exposed in the excavation were retained by a proprietary geo-grid/ mesh pinned into the slope, to mitigate the risk of rock fall.
